I noticed that the dyno figures on your web site are for a fully kitted engine. What most of us will be looking for are headers that work with an open air cleaner and a chip if that one ever transpires. I will purchase your headers if they broaden the existing torque/HP curve or at least do not lessen our power below 2500 RPM. I think the vast majority of X owners use it as a daily driver and weekend wheeler. I may be wrong on that point but hope that market was included in the development of your exhaust.
I also would like to know if running dual pipes all the way out would be of any value. If so what diameter would you suggest? How about a balance pipe? I'm not familiar with the scavenging effects of 3 cylinder banks.
And last, any MPG estimates? Dangerous territory I know.
Tell me great power huge MPG and I'll order them tomorrow.

Thank's
